SDI Distribution Amplifiers and 12G SDI Splitters

SDI Distribution Amplifiers and 12G-SDI Splitters

SDI Distribution Amplifiers (DAs) and 12G-SDI splitters are used to route a single SDI video signal to multiple outputs without degradation. While these terms are often used interchangeably, technically, a splitter duplicates a signal, whereas a distribution amplifier actively splits, amplifies, equalizes, and re-clocks it to maintain signal integrity. SDI Distribution Amplifiers (standard SDI) are active professional video devices that split a single SDI input into multiple identical outputs while preserving signal strength and quality. They use built-in equalization to compensate for cable loss over long distances, re-clocking to remove jitter and restore clean timing, and output isolation to prevent faults on one line from affecting others. Depending on the format (SD, HD, or 3G), they can support transmission distances of up to 400 meters, making them ideal for reliable signal distribution in broadcast and production environments. Markertek in-house experts are ready to help you get the solution you need.

12G-SDI Splitters
12G-SDI Splitters (Distribution Amplifiers) are high-bandwidth professional video devices that distribute a single 12G-SDI input (11.88 Gbps) to multiple outputs while supporting 4K UHD (2160p) at 60 fps over a single coaxial cable. They feature automatic re-clocking and equalization to maintain signal integrity, typically in 1x2, 1x4, or 1x8 configurations, and are multi-rate compatible with SD, HD, 3G, and 6G-SDI standards. In addition to video, they pass embedded audio, timecode, and HDR metadata, support transmission distances of up to 70 meters before requiring further amplification, and simplify modern 4K workflows by replacing older "quad-link" 3G-SDI setups with a single-cable solution.

Common Applications Are:

• Broadcast Control Rooms
• Live Sports & Mobile Productions (OB Vans)
• Digital Imaging Technician (DIT) Carts
• Medical Surgery Suites
